It may be due to swelling of the sludge, which is not serious. But I am very surprised that the MLVSS of the biochemical tank is about 2000mg/l, the sludge age is relatively short, the sludge is not aging, and it is within the control range. The ...
Prediction of sludge bulking using the knowledge-leverage-based fuzzy neural network

Pile Cloth Media Filtration System
The pile fibres used in this patented process are comparable in their structure to an animal fur. During filtration the individual pile fibres lie flat to form a dense and effective barrier to suspended solids. During backwash, the fibers briefly stand vertically inside the suction header, so that the retained solids are easily removed. By using the filtration capabilities of the very fine fibres ...
